Kauri

New Zealand's most massive native tree by volume, capable of living well over 1,000 years, but naturally restricted to Northland, Auckland and the Coromandel, the warm northern parts of the country where it grows wild. Kauri dieback, a soil-borne disease with no cure that has devastated wild kauri populations, makes hygiene genuinely important even for garden specimens: avoid bringing in soil from elsewhere, and clean footwear and tools between garden visits if you've been near affected bush. Very slow-growing and, like rimu, essentially a legacy planting rather than a quick garden feature.

When to plant by region

In Whangārei / Northland, Auckland, Tauranga / Bay of Plenty, Gisborne and Napier / Hawke's Bay: September-October.

Growing stages

  1. Planting & establishmentSpring

    • Best suited to Northland, Auckland and the Coromandel; further south it's more marginal and slower to establish
    • Use clean, bought-in soil and potting mix rather than soil moved from elsewhere, to avoid introducing kauri dieback disease
    • Choose a full-sun spot with well-drained soil and allow generous long-term space

  2. Early growthFirst several years

    • Growth is very slow, patience is needed, as with most native conifers
    • Clean footwear and tools between visits to bush areas before working near the tree, as kauri dieback spreads in soil
    • Water during dry spells while the root system is still establishing

  3. Maturing growth

    • Generally free of significant pests, though ongoing biosecurity care around kauri dieback remains important throughout the tree's life
    • Continue allowing space as the canopy slowly develops
    • Avoid disturbing soil around the root zone unnecessarily

  4. Long-term maturity

    • A genuinely multi-generational tree, even well-established garden specimens remain young relative to the tree's natural lifespan
    • Kererū feed on the fruit of mature trees, though this is typically many decades away for a garden-planted specimen
    • Continue practising basic kauri dieback hygiene for the life of the tree, since there is still no cure once a tree is infected
